Water Leaching Kinetics of Boron from the Alkali-Activated Ludwigite Ore

Molecules, Год журнала: 2024, Номер 29(4), С. 826 - 826

Опубликована: Фев. 12, 2024

The primary aim of this study was to investigate the boron leaching process from alkali-activated ludwigite ore. Initially, ore underwent activation through roasting at 1050 °C for 60 min with 20% sodium carbonate. Subsequently, examined influence parameters, including temperature, time, liquid-to-solid ratio, and particle size, using activated as raw material. Additionally, water characteristics residues kinetics were analyzed. results demonstrated that efficiency reached 93.71% reduced under specific conditions: temperature 180 °C, time 6 h, ratio 8:1, feed size 52.31 μm (average size). Leach residue indicated dissolution minerals during process. behavior followed Avrami Equation, equation derived by fitting data. Moreover, energy (Ea) value determined be 8.812 kJ·mol−1 Arrhenius indicating is controlled diffusion.

Zintl Clusters as a Platform for Lewis Acid Catalysis

Inorganic Chemistry, Год журнала: 2024, Номер 63(43), С. 20117 - 20125

Опубликована: Май 30, 2024

Clusters of the main group elements phosphorus and arsenic, commonly categorized as Zintl clusters, have been known for over a century. And, only now is application these systems catalysts organic synthesis being investigated. In this work, boranes are tethered via an aliphatic linker to Zintl-based clusters their Lewis acidity examined experimentally, by Gutmann–Beckett test competency in hydroborative reduction six substrates, well computationally, fluoride ion affinity hydride methods. The effects tuning length, substituents at boron, changing cluster from seven-atom system arsenic on reactivity studied.
